Description

The invention relates to radio electronic technology and relates to the improvement of special technological equipment, in particular, for the transportation of radio components with unidirectional leads and their connection to the control measuring unit.

The purpose of the invention is to improve the performance and reliability of installation of the radio components in the cassette sockets. This is achieved by the fact that the device is equipped with mechanisms for breeding outlets of radio components, and the stores are equipped with stepper drive, movement along the conveyor with the cassettes by half a step or the whole step of the arrangement of their channels.

FIG. 1 shows the kinematic diagram of the device; in fig. 2 — view A in FIG. one; in fig. 3 - 6 - the mutual arrangement of the nodes of breeding vyshdo and unloaded channels.

The device consists of a conveyor with a pre-drive drive, on branches x of which are fixed with a certain pitch of cartridge I. Control-measuring units 2 are placed above the conveyor, electrically connected to the terminal clamps of cassettes 1, and under the conveyor - hoppers 3 for receiving controlled radio components.

The loading device consists of structurally similar magazines: unloading 4 and loading 5, installed above conveyor cartridges on guides 6 with the possibility of independent offensive movement of each magazine, provided by differential mechanisms consisting of a gear wheel 7, p & Lindra 10 and 11 respectively.

Each store has a number of vertical channels 12 arranged with a pitch t from each other, in which radio components 13 are placed, and their terminals 14 are located in the through slots of the stores.

For larger stores, the pitch t of their channels is two times smaller than the pitch T of the arrangement of the contact cassettes 1 on the conveyor belt, which cannot be reduced structurally.

Each channel 2 of the store is equipped with an individual retainer 15, made in the form of a flat spring.

The latches 15 of the magazine 4 interact through the sliders 16 and the lever 17 with the pneumatic cylinder 18, and the latches of the store 5 through the slider 19 and

5 pin 20 - with pneumatic cylinder 21. The sliders 16 and 19 are arranged in increments equal to the step T of the cassettes 1. Under the magazine 4 there is a fixed support 22, and under the magazine 5 there is a pusher 23 connected to the pneumatic cylinder 24, In the support 22 and the pusher 23 there are slots, the width of which is slightly larger than the diameter of the parts of the radio components for passing the latter during re-stacking. Under magazines 4 and 5, there are also two mechanisms for clamping and moving radio components 13. One of them is designed to transfer radio components from magazine 4

20 in cassettes, consists of a housing 25, spring-loaded grippers 26 arranged in increments equal to the pitch T of the cassettes 1, and interacting with a pneumatic cylinder 27 located on the housing 25, as well as a plug 28 fixedly connected with the housing 25.

The other, structurally similar to the first one and intended to remove the monitored radio components from the cassettes 1 and transfer them to the store 5, consists of a housing 29, grippers 30 interacting with a pneumatic cylinder 31 located on the housing 29, and a fork 32 fixedly connected to the housing 29 .

The housing 25 is hinged on the levers 33, on one of which a gear wheel 34 is fixedly mounted, which is engaged with the sector 35 connected to the pneumatic cylinder 36.

The housing 29 is hinged on the levers 37, on one of which the gear wheel 38 is fixedly mounted, which is engaged with the sector 39 connected to the pneumatic cylinder 40.

The forks 28 and 32, with their grooves, embrace a fixed finger 41. On the outside of each store, brackets 42 and 43 are attached to each other in pairs.

The brackets 42 are mounted on the axles in pairs between the channels of the mag- net 4 with a step equal to the pitch of these channels, the levers 44 interacting with each other and kinematically connected with the help of a plug 45, a finger 46 with a pneumatic cylinder 47. The levers 44,

plug 45, pin D6 and pneumatic cylinder 47 form a node for diluting capacitor leads.

On the shafts mounted in the brackets 43, there are located in pairs between the channels of the store 5 with the same pitch levers 48, interacting with each other and kinematically connected with a plug 49, a finger 50 with a pneumatic cylinder 51. Levers 48, fork 49, a finger 50 and pneumatic cylinder 51 form a condenser lead-down unit.

The levers 44 are designed to dilute the leads 14 before loading the radio components into the cassettes 1, and the levers 48 to bring the leads 14 together before putting the radio components into the store 5. The number of pairs of those and other levers corresponds to the number of channels in the stores.

Before starting work on the supports 6, a magazine 4 is installed with radio components intended for control, and a shop 5 for transferring to it the radio components of the corresponding nominal value. In this case, the levers 44 and 48 are located between the channels 12 of the shops (FIG. 3).

The transfer of the radio components 3 from the magazine 4 to the contact cassettes I of the conveyor belt and from them, after checking to the magazine 5, is carried out at the moment the conveyor is stopped. The cycle first removes the radio components 13 that have passed the test from the cassettes 1, if they are there, and then loads the radio components into the cassettes from the shop 4 for inspection.

Consider the operation of the mechanisms of the device from the cassette loading cycle. By the time the conveyor is stopped, the grips 26 are positioned under the channels 12 of the magazine 4, and the grips 30 are below the channels of the shop 5.

The pitch of the grips, as well as the sliders 16 and 19. is equal to the pitch of the cassettes 1, which is equal to the double pitch of the channels in the stores. Therefore, the removal of radio components from one store and their transfer to another after control is performed per cycle in only half of the channels through a step (Fig. 3 and 5), followed by mixing

stores one step back and forth. one

a certain value, after which the retainers) 5 are retracted by the sliders 16 through the lever S 7 under the action of the pneumatic cylinder 18, the lower radio components 13, which are located in the channels 12 of the shop 4, under the action of gravity are lowered onto the unsupported support 22 in the clamps 26, the retainers 15 return to their original position 5 by holding down the pillars of radio components from falling out.

The radio components caught in the grippers 26 are compressed by them during the return stroke of the pneumatic cylinder stem 27. Then the pneumatic nebulizer rod 10 mixes the rail 9, rotates the wheel 7, relative to the fixed rail B, moving the magazine 4 and into the levers 44 and 44 a half-step of the channels in a position where the lugs of the levers 44 are located between the terminals 14 of the radio components located in the grippers 26 (Fig. 4). The pneumatic cylinder 47 and the php-1ag 44 are switched on using plugs 45 and bolts 45 at the same time, the terminals are separated: radio components.

Then the levers 44 are reduced and at the same time the pneumatic cylinder 36 is turned on, the sector 35 is turned, the wheel is FOR and the frame is fixed with the wheel 34 of the lever: g 33; which turns the body 25 from B: -; LOCK 28 is relatively non-, under: and;: a-the 1st finger 41 and translates it into the position shown in FIG. 2

At this point, slots on cassettes 1, special

mechanism. The 4 radio components of the hubs go down into these sockets, then the last ones are closed with a special mechanism, the grippers 26 open and the levers 33 retract the housing 25 to its original position.

As the grippers 26 are raised above the radio components, it is turned on. the conveyor, the supply of a new row of cassettes 1 for unloading and loading, and a new row of channels 12 are set above the grippers 26 by moving the magazine 4 relative to the grippers 26 to a step equal to the channel position using the rail 8 rotating the wheel 7 relative to the fixed rail 9 under the action of the pneumatic cylinder 11, and half a step with the rail 9 relative to the rail, 8 under the action of the pneumatic cylinder 10.

The removal of the radio components 13 from the cassettes 1 is carried out after they pass the control which is carried out by connecting the radio components to the control and measuring units 2.

One of the ratings of the radio components is passed under the transfer provided by the technology for other operations (e.g. marking) using the magazine. The remaining radio components are dumped by dump mechanisms into receiving hoppers 3.

By the time the conveyor stops, the clamping mechanism for transferring the monitored radio components to the mage ZIN 5 is transferred to a position similar to that of the clamping mechanism for transferring radio components from the magazine 4 to the cassette 1 at the moment of loading, turning on the pneumatic cylinder 40 through sector 39, wheel 38 ,. the levers 37 unfolds the housing 29 with the plug 32 relative to the finger 41. In this case, the grippers 30 under the action of the pneumatic cylinder 31 open. The grips 30 in their lower position embrace radio components 3.

The pneumatic cylinder 31 is turned on, and the grippers 30 catch the radio components. By a special slot mechanism in cassettes, the body 29 is moved in the opposite direction. The radio components in the grippers 30 are transferred to the upper position and are located between the pusher 23 and the magazine 5 between the channels 12 of the magazine 5, and the outputs of the radio components fall between the levers 48. The pneumatic cylinder 51 is turned on.

With the help of the plug 49 and the finger 50, the levers 48 are turned towards each other, squeezing apart before loading. Then the rail 9 is moved by the pneumatic cylinder 10 of the differential mechanism, moving the magazine 5 and the levers 48 associated with it by half a step. The channels 12 of the magazine 5 are installed at the end of this movement, directly above the radio components located in the grippers 30.

The pneumatic cylinder 21 is engaged, which retracts the latches 15 With a crawler. new 19 and lever 20, and pneumatic cylinder 24, which pusher 23 moves the radio parts from grippers 30 to channels 12 of magazine 5. Then clamps 15 and pusher 23 return to the outset 496

the position, and the magazine 5 with the rails 8 and 9 is moved to a new position to load other channels. The positions of magazine 5 with levers 48 and shop 4 with levers using differential mechanisms alternate each cycle. This allows unloading the store and transferring the monitored radio components to the magazine, whose channel pitch is different from the location of the contact cassettes 1, and, apart from the toga, dissolve and reduce the outputs of the radio components, when they are between channels, without interference from the radio components. being in channels.
